Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31204, here are decompositions:
- 11 + 31193 = 31204
- 23 + 31181 = 31204
- 53 + 31151 = 31204
- 83 + 31121 = 31204
- 113 + 31091 = 31204
- 191 + 31013 = 31204
- 227 + 30977 = 31204
- 233 + 30971 = 31204
Showing the first eight; more decompositions exist.
